Cleveland C96019 Spiral Point Tap 3/8-24 UNF
This Cleveland C96019 spiral point tap cuts 3/8-24 UNF threads in through-holes using a right-hand plug design. The cobalt construction with Hard Lube coating supports long tool life in tough materials. Three flutes provide efficient chip evacuation forward through the hole. The overall length is 3 15/16 in with a thread length of 1 47/64 in.
Best for machinists cutting unified fine threads
Suited for professionals producing 3/8-24 UNF threads to a 2B class of fit in through-hole applications. The spiral point geometry pushes chips ahead of the tap, so it is not designed for blind holes where chips must be pulled out. Buyers needing bottoming or taper chamfers, left-hand threads, or larger diameters should select a different tool.
Verify hole size and holder compatibility
Confirm the drilled hole matches the 75 percent thread drill size of 8.50 mm before tapping. Ensure your tap holder accepts the shank of a 3 15/16 in overall length tool. Check that the machine spindle runs right-hand rotation for this thread direction. The thread limit is 2B; verify this tolerance meets the drawing requirements.

Questions about this item
What tap drill size do I need to prepare before using this 3/8-24 UNF spiral point tap?
Use an 8.50 mm drill for a 75 percent thread to match the tap specification.
Can this 3-flute cobalt tap handle the same materials as my older high-speed steel taps?
Cobalt construction gives better heat resistance and wear life than standard high-speed steel on tough alloys.
How do I verify the thread limit is correct after tapping a hole with this tool?
Check the finished thread with a 2B class-of-fit gauge to confirm it meets the 2B thread limit.
